TOFO:
The fact that some of you think that this is some sort of youtube video you can just pause, so's you can pop up and pick up some fuel, just goes to show that you know absolutely the square root of **** all that you are blithely spouting pure sh1te about.
You are indeed quite right. The only patrolling I have done was on two feet on land. I can usually identify a submarine 3 times out of 10 at a range of 6 feet!
So, what is the correct solution, what is the budget for that solution and what's the expected timeframe to implement said solution?
